After connecting to my home lab the day before, today no dice.
Connecting from the same site as yesterday, I enabled the hotspot on my iPhone and connected my laptop to the personal WiFi.
At that point I could bring up the vpn to back home.
At the router I issued show vpn debug to check things out. To my surprise I found the router still had an active SA from my last connection.
Security Associations (1 up, 0 connecting): remote-access: ESTABLISHED 9 hours ago,
I was able to break down this SA by issuing restart vpn from a non-global configuration prompt. In other words, do not bother issuing this command in configure mode. Ensure your terminal looks like you@edgerouter:~$
